Abstract
The invention refers to a large caliber plastic steel strip compound windup tube section material. It is made up of steel strip 4 and steel trip 3, plastic 2 and plastic 1. The steel strip 4 and the steel strip 3 is jointed together with roller-argon-FI. When plastic extruding to cover the steel strip, the section material in/out plastic and the steel strip would joined together the plastic passing through the connect point of the steel strip hole to solve the connection of the different material. When the section material is made up to windup tube, one end of the section material connects to the other end, and the bond should be jointed by roller-argon-FI. Then, the weld would by covered by plastic after plastic extruding. The heavy caliber plastic steel strip compound windup tube manufactured by the section material means using small machine to produce big tube. The technology is easy to be controlled; the method is simple and convenient, the windup tube has high compressive strength and sealing anti-seep function; it also saves material and decreases the cost. The section material is mainly used for metro- ceiling coil, cement duct repairing, water supply, drainage, flood discharging, petrol delivering and gas transmission pipe.
Description
Technical field
Patent of the present invention relates to a kind of large diameter pipeline section bar, and more particularly, it relates to a kind ofly carries out the large-bore plastics steel band composite winding pipe section bar that physics is composited with plastics and steel band.
Background technique
At present, sell various multiple tubes on the market, as: aluminium-plastic composite pipe, plastic steel composite pipe, though these composite pipes have solved the corrosion-resistant and not enough weakness of plastic tube rigidity of metallic material, bigger improvement and breakthrough are arranged, but they all are to make and use in small-bore scope on the pipeline industry.Up to the present, on market, do not see as yet and both solved anticorrosive metal, solve the heavy caliber plastic-steel composite winding pipe of plastics insufficient strength again.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of simple in structure, utilize small machine production to be easy to manufacturing, both solved anti-corrosion of metal, solve the not enough large-bore plastics steel band composite winding pipe section bar of plastics rigidity again.
Large-bore plastics steel band composite winding pipe section bar of the present invention comprises the isosceles trapezoid steel band of the burr that the roll extrusion of outer wall process forms and the steel band and the plastics of the burr that the roll extrusion of outer wall process forms.The steel band section bar of this plastic overmold is wound in large-bore plastics steel band composite winding pipe through spiral, described heavy caliber steel band composite winding pipe section bar outer wall is plastics, section bar hollow is steel band, and the effect of plastics is anticorrosion, and the effect of steel band is the rigidity that increases after section bar is wound in tubing.
The invention has the beneficial effects as follows:
(1) with the big tubing of small machine production;
(2) reliability height, corrosion protection, good rigidity, long service life;
(3) simple in structure, be easy to make;
(4) hollow structure, economical with materials, cost is low.
Description of drawings
Fig. 1 is the steel band of the outside band burr of process roll forming before large-bore plastics steel band composite winding pipe section bar of the present invention is shaped.
Fig. 2 is the steel band of process roll extrusion bottom side band burr before large-bore plastics steel band composite winding pipe section bar of the present invention is shaped.
Fig. 3 is that large-bore plastics steel band composite winding pipe section bar of the present invention is shaped through the combination of welding back Fig. 1 and Fig. 2.
Fig. 4 is the structural drawing that is coated on the large-bore plastics steel band composite winding pipe section bar of the present invention that forms on Fig. 3 through extrusion molding.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
In the drawings, large-bore plastics steel band composite winding pipe section bar mainly is made of by steel band hole tie point 6 and 6-A and hollow 7 argon fluorine weldering tie point 5-A between argon fluorine weldering tie point 5, the steel band between section bar plastics 1, plastics 2, steel band 3, steel band 4, the steel band, plastics.
The burr of described large-bore plastics steel band composite winding pipe section bar steel band 3 outsides for forming through roll extrusion.Purpose is exactly the adhesion that solves plastics and steel band, the burr of steel band 4 bottom sides for forming through roll extrusion, steel band 3 and steel band 4 are connected into Fig. 3 by the weldering of argon fluorine, coat large-bore plastics steel band composite winding pipe profile structure Fig. 4 that Fig. 3 forms patent of the present invention through extrusion molding.In this structural drawing, 5 is argon fluorine weldering tie point between the steel band, by welding two steel bands is linked together.6 places are that plastics connect by steel band, and plastics coat steel band through via hole, form an integral body, the connection that has solved two kinds of materials.
Described Fig. 4 twines through spiral two ends, the left and right sides steel band of this section bar is overlapped mutually, argon fluorine weldering tie point carries out the welding of roller type argon fluorine between overlapped points 5-A place is by steel band, by extrusion molding steel band phase lap-joint is coated, the plastics that this time extruded make plastics pass through steel band hole by the steel band hole at tie point by the 6-A plastics of reserving and give inner-walls of duct and outer wall filled plastics again.Described steel band hole is that extrusion molding connects by the steel band hole, plays rivet clasp, solves the physical connection of plastics and steel band effectively, and the two is securely connected together, and solves the connection of two kinds of different materials.
